JK触发器,英文名称为JK flip-flop,是数字电路触发器中的一种基本电路单元,具有置0、置1、翻转和保持的功能,是各集成触发器中功能最为齐全的,具有很强的通用性和无需考虑一次变化的特点,且其能较为灵活地转换成D触发器、T触发器等其他类型的触发器。 2018-02-08 14:51:32 四种...
Fig. 1. Typical JK Flip-Flop datasheet truth table. The basic truths mentioned do not account for the reset (R) input which gives the flip-flop an initial state when the reset is held low. The term “irrelevant” is used in the datasheet with respect to the clock and JK inputs when...

Basically, a Flip-Flop is expected as edge triggered circuit, the output must not change it's state on an input change other than an active clock edge (without considering additional asynchronous control inputs). The present circuit however changes it's output state outside active clock edges....
